Historically, HW -> HW uploads did not exist, so the current code assumes they will never happen. But as part of introducing Vulkan support into ffmpeg, we added HW -> HW support to enable transfers between Vulkan and CUDA. Today, that means you can use the lavfi hwupload filter with the correct configuration (and previous changes in this series) but it would be more convenient to enable HW -> HW in the format filter so that the transfers can be done more intuitively: ``` --vf=format=fmt=cuda ``` and ``` --vf=format=fmt=vulkan ``` Most of the work here is skipping logic that is specific to SW -> HW uploads doing format conversion. There is no ability to do inline conversion when moving between HW formats, so the format must be mutually understood to begin with. Additional work needs to be done to enable transfers between VAAPI and Vulkan which uses mapping, rather than uploads. I'll tackle that in the next change. |
